Fig. 5. The angular direction change
COM in COM velocity
decreased with increasing arc foot radius
. COM direction change was
estimated as the angle between the steepest upward and downward velocities of
the COM in the sagittal plane (defined below; compare with
Fig. 1B). The relationship
between
COM and
is described well by the linear fit of
Eqn 9, r2=0.89. Different coloured symbols indicate
different subjects.
